Alzheimer's disease （AD） is an age-related neurodegenerative disease that belongs to the category of dementia in traditional Chinese medicine （TCM）. According to the TCM theory， phlegm， dampness， stasis， and toxin are the major factors inducing the occurrence and development of AD. The application of aromatic Chinese medicines to remove the combined phlegm， dampness， stasis， and toxin is an important TCM method for treating AD. Aquaporins （AQPs） are involved in the water metabolism of the central nervous system （CNS）， playing a role in the water balance of CNS. Therefore， AQPs are deeply involved in the occurrence and development of AD. AQPs may be the key targets of a variety of aromatic Chinese medicines. From the intrinsic relationship between AQPs and AD-inducing factors （phlegm， dampness， stasis， and toxin）， this study explores the modern medical connotation of treating AD with aromatic Chinese medicines， aiming to provide ideas for the prevention and treatment of AD with TCM.

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months， which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset，and rapid changes，which coincides with the characteristics of refractory angina which is complex and changeable，prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation， with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine （TCM） employs a holistic approach known as "activating blood circulation and removing toxins"， which is supplemented by various methods to tonify Qi and warm Yang， nourish the kidneys and invigorate the spleen， clear heat and transform phlegm. This approach applies anti-inflammatory measures， regulates lipid metabolism， inhibits oxidative stress and thrombus formation， protects endothelial function in blood vessels， as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore，based on the theory of "stasis and toxin"，combined with TCM theory and modern medical research，this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM，and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris，coronary microvascular dysfunction，coronary artery spasm and obstructive coronary artery disease，hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.

ObjectiveTo screen and establish animal models of combined stasis and toxin syndrome based on the comparison of three modeling methods， i.e.， carrageenan （Ca）， Ca combined with dried yeast （Ca+Yeast）， and Ca combined with lipopolysaccharide （Ca+LPS）. MethodForty SPF male SD rats were randomly divided into normal group， Ca group， Ca+Yeast group， and Ca+LPS group， with 10 rats in each group. The Ca group， Ca+Yeast group， and Ca+LPS group received an intraperitoneal injection of Ca （10 mg·kg-1） on the first day. The Ca+LPS group received an intraperitoneal injection of LPS （50 μg·kg-1） on the second day， and the Ca+Yeast group received a subcutaneous injection of dry yeast suspension （2 mg·kg-1） on the back on the second day. The rectal temperature of each group was dynamically observed after modeling. After 24 hours of modeling， the macroscopic evaluation indexes， including tongue manifestation， pulse， and black tail length in each group were observed. The PeriCam PSI imaging system was used to detect the blood flow perfusion of the rat tail. The automatic hemorheology analyzer was used to measure the whole blood viscosity and plasma viscosity of each group. The PL platelet function analyzer was used to detect the platelet aggregation rate of the rats. The enzyme-linked immunosorbent assay （ELISA） was used to detect the interleukin-6 （IL-6） level in the rat plasma. The myocardial tissue， brain tissue， and lung tissue of each group of rats were observed by hematoxylin-eosin （HE） staining. ResultCompared with the normal group， all three model groups showed varying degrees of black tail （P<0.05， P<0.01）， reduced blood flow perfusion at the tail end （P<0.05， P<0.01）， decreased R， G， and B values of tongue manifestation （P<0.05， P<0.01）， and increased maximum platelet aggregation rate （P<0.05， P<0.01）. The pulse amplitudes of the Ca+Yeast group and the Ca+LPS group were lower than that of the normal group （P<0.05， P<0.01）. In addition， the average rectal temperature of the Ca+Yeast group increased after 24 hours of modeling （P<0.01）， and the low-， medium-， and high-shear whole blood viscosity and plasma viscosity increased （P<0.05， P<0.01） as compared with those in the normal group. Additionally， the expression level of the plasma inflammatory factor IL-6 was significantly up-regulated （P<0.05）. Pathological morphology results showed that the Ca+Yeast group had the most severe pathological changes， with small foci of myocardial fiber dissolution， inflammatory cell infiltration， and fibroblast proliferation observed. In the hippocampal area， the neurons were sparse and had undergone red degeneration. In the small focus of the lung interstitium， lymphocytes and neutrophils were infiltrated. ConclusionThe animal model of combined stasis and toxin syndrome was properly established using Ca+Yeast. The systematic evaluation system of the model， which includes traditional Chinese medicine four diagnostic information， western medicine microscopic indicators， and tissue pathological morphology， is worthy of consideration and reference by researchers.

Objective::To observe the clinical efficacy of Dahuang Zhuyu decoction for oral administration and enema on severe acute pancreatitis with syndromes of blood stasis and toxin and its effect on serum inflammatory factors. Method::Sixty eight patients with severe acute pancreatitis with syndromes of blood stasis and toxin who were admitted in Henan Provincial People's Hospital from September 2017 to December 2018 were randomly divided into treatment group (34 cases) and control group (34 cases). The control group was treated with western medicine. The treatment group was treated with Dahuang Zhuyu decoction for oral administattion and enema in addition to the therapy of the control group. Both groups were treated for 7 days. Before and after treatment, abdominal pain, bloating, nausea and vomiting were scored separately, serum amylase (AMS), lipase (LPS), interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) were detected, and abdominal pain disappearance time, bloating disappearance time and exhaust recovery time were recorded. Result::After treatment, the abdominal pain score, abdominal distension score, nausea and vomiting score, serum AMS, LPS, IL-6 and TNF-α were lower than those before treatment (P<0.05), and those in treatment group was lower than those in control group (P<0.05). After treatment, IL-10 level in both groups was higher than those before treatment (P<0.05), and that in treatment group was higher than that in control group (P<0.05). The disappearance time of abdominal pain, the disappearance time of abdominal distension and the recovery time of exhaust were shorter in treatment group than in control group (P<0.05). The total effective rate of the treatment group was higher than that of the control group (P<0.05). Conclusion::Dahuang Zhuyu decoction for oral administration and enema for severe acute pancreatitis with syndromes of blood stasis and toxin can alleviate clinical symptoms, reduce amylase and lipase levels, inhibit the expression of pro-inflammatory factors, promote the expression of anti-inflammatory factors, restore intestinal function, and improve clinical efficacy.

OBJECTIVE@#To investigate the effects of Zhizi Chuanxiong Capsule (ZCC, ) on abnormal DNA methylation in a rabbit model of atherosclerosis (AS).@*METHODS@#After 1 week of adaptive feeding, 48 New Zealand white rabbits were randomly divided into 4 groups: a control group (n=12) fed with normal diet for 22 weeks; a model group (n=12) fed with high fat diet for 14 weeks followed by 8 weeks of normal diet feeding; a low-dose ZCC group (n=12) fed with high fat diet and low-dose ZCC for 14 weeks, followed by 8 weeks of normal diet and low-dose drug; a high-dose ZCC group (n=12) fed with high fat diet and high-dose drug for 14 weeks, followed by 8 weeks of normal diet and high-dose drug. After 22 weeks of feeding, blood samples were taken from the rabbit ear vein, and the genomic DNA was extracted for methylation immunoprecipitation sequencing (Medip-seq). The aorta tissues were collected for hematoxylin-eosin (HE) staining.@*RESULTS@#Eight rabbits died during the feeding process. HE staining showed that the size of the lipid deposition on vessel wall and atherosclerotic plaque formation were reduced in both low- and high-dose group. The Medip-seq results showed that there were 146 abnormally methylated genes (including both hypermethylated gene and hypomethylated genes) in the model group, compared with the control group. Gene Ontology (GO) and Pathway analysis showed that these abnormally methylated genes were found to be involved in multiple AS-related functions and pathways, such as protein kinase C activity, cholesterol transport, mitogen-activated protein kinase (MAPK) signaling pathway, peroxisome proliferater-activated receptor signaling pathway, vascular smooth muscle contraction, inflammation and so on. The abnormal methylated genes in AS model group were altered in both low- and high-dose groups: low-dose ZCC could change 72 of the 146 abnormally methylated genes, high-dose ZCC could change 71. Through GO and Pathway analysis, these altered methylated genes were involved in protein kinase C activity, inflammatory pathway, MAPK signaling pathway, vascular endothelial growth factor signaling pathway, etc. CONCLUSION: ZCC could treat AS through regulating the abnormal hypermethylated and hypomethylated genes in AS rabbit model.
